Title: Improvements in or relating to the manufacture of hexagonal slugs
Inventor: ELLIOTT JAMES REED
IPC: B21D28/06
Filed: 1968-07-26
Abstract: 1,212,275. Punching. JOHN DALE (FOUNDRIES) Ltd. 23 July, 1969 [26 July, 1968], No. 35925/68. Heading B3W. Hexagonal slugs are punched out of aluminium sheet or strip by two lines of hexagonal punches and dies staggered and spaced so that the whole width of the strip between the outermost punches and dies is cut into hexagons without waste. Strip material fed between guides 8 to a first line of punches and dies (dies 13a-13c shown) until it contacts gauging stops 21 and a first punching stroke, is performed. The sheet is advanced, the stops 21 now acting as side guides, and further punching strokes are performed. Since the second line of punches only have to shear the trailing edge of a hexagon to form a slug the dies 14a and 14b have apertures shaped to retain one or more slugs from the preceding punching strokes to prevent the partially severed slug from tilting during punching. The strip may be punched by circular punches and dies (dies 10 shown) before the slug-blanking operation to form slugs each with a central hole, pilot pins (17), (Figs. 1 and 3, not shown) being provided in the first line of punches for locating in the holes. The pins may be resiliently mounted in the punches and may be removable or punches may be replaced by pilot-less punches it non- apertured slugs are to be produced. Alternatively, pilot pins may be mounted in the upper bolster between the two lines of punches and dies to locate in holes punched at a previous stroke by the first line of punches. The stop arrangement may include portions between the stops 21 for engaging the three flats forming the forward edge of each of the parts of the strip underlying the punches of the second line. A stripper plate (20), Fig. 1 (not shown), is provided.

Title: Improvements in catalytic bed assemblies
Inventor: LANE BERNARD FREDERICK ADAMS
IPC: B01J35/02
Filed: 1954-12-15
Abstract: <PICT:0780342/III/1> A catalytic bed assembly for decomposing fluids, e.g. hydrogen peroxide for driving rocket motors, comprises a reaction chamber with a stack of pellets at the inlet, and a stack of gauzes at the outlet, the pellets and gauzes being made of or plated with a catalytic metal, e.g. silver.  This assembly ensures a high activity and life to the pellets at the cooler inlet zone.  A casing 10, Fig. 1, provided with an inlet 14 for hydrogen peroxide, and outlets 15 for the products of combustion is divided into roughly equal sized chambers by grids 18, 19, and a distributing plate 20. The inlet zone has mounted therein a perforated inner cylinder 23, having perforated partition walls mounted radially and extending to the cylinder wall 16, forming chambers to contain pellets 27.  The pellets are preferably made of sintered silver powder of particle size 0.007 in. to 0.01 in. mixed with copper powder of 300 mesh; the pellets are 3 mm. diameter 1.5 mm. thick, and are anodized.  The zone between grids 18, 19 is packed with gauze sheets 28 of 20 mesh and are made of 28 S.W.G. copper wire, spray coated with silver.  A gauze of heavy gauge is mounted against grids 18, 19.  Hydrogen peroxide is uniformly distributed into the zone of tightly packed pellets, where it is partly decomposed exothermically, and the products then flow into the gauze-filled zone where decomposition is completed at higher temperatures and gas velocities, and the products of steam and oxygen issue through outlets 15. Specification 761,234 is referred to.

Abstract: 879,749. Engine turning gear. BAYARD, G. Oct. 27, 1959 [Nov. 13, 1958], No. 36467/59. Class 7(5). [Also in Group XXVI] An arrangement for starting gas turbine engines comprises a unit including a gas turbine 1, a compressor 2, and a combustion chamber 4, which unit supplies a starter turbine 5, means being provided to cut off the fuel supply to the turbine 1 when the compressor discharge pressure of the engine to be started reaches a predetermined value. The starter turbine 5 drives the engine to be started through a reduction gear 6 and a clutch 7. The compressor 2 and the gas turbine 1 are connected co-axially by a shaft 3 which is actuated by an electric motor 9 or other prime mover of reduced power. The fuel supply to the combustion chamber 4 is controlled by an electrically actuated valve itself controlled by a pressure sensitive switch, the arrangement being such that the fuel valve is closed as soon as the discharge pressure of the engine to be started attains the predetermined value to which the pressure switch has been set and at which the engine is self-sustaining. The complete starting arrangement is conveniently housed in the front section 8 of the gas turbine engine to be started.

Abstract: 177,273. Kimura, R., and Seisakusho, T. Dec. 30, 1920. Addition to 168,695. Alternating-current motors; brush - holders; collecting-rings.-In apparatus of the type described in the parent Specification for removing the brushes from induction-motor slip-rings and short-circuiting the windings, the spider that carries the rings is automatically moved by centrifugal means to carry them away from the brushes and short-circuit the rings at a predetermined speed. Fig. 3 shows a plan view, Fig. 1, a longitudinal section, and Fig. 2 sections on the lines A C, D B, and E F, of Fig. 1 in the righthand upper and lower halves and left-hand half respectively. The insulated rings 4, 4<1> are carried on arms 2 of a hub 3 which slides on the shaft and is normally pressed by a spring 17 against the fixed brush bracket 20. One long and two short short-circuiting pieces 7 are screwed to the ring 4 at 8 and one long one 7<1> is screwed to the ring 4<1> at 8<1>. These, together with the shaft 1 of the rotor 11 form the terminals of the windings a, b, c, as shown in Fig. 8. The pieces 7, 7<1> co-operate with two short tongues 9 carried by a lower fixed curved member 15 and with two long tongues 9, 9<1> on an upper member 15, both members being screwed at 13 to arms 12 of the rotor so as to rotate therewith. The long pieces 7, 7<1> always contact with the long tongues 9, 9<1> and the short pairs only engage when the hub and rings 4, 4' move axially to the position shown in dotted lines in Fig. 1. This movement is effected by centrifugal arms 36 pivoted to the members 15 at 39 and linked at 32 to pivots 33 on the spider .arms 2. The leads c, b, Fig. 8, are connected at g, h to the short tongues 9 so that the engagement of these tongues with the short pieces 7 short-circuits the windings. The inflated brush boxes 23 are carried by a bracket 20 which straddles the shaft, and pins 26 in the brushes, by engaging slots 27 in the box sides under the action of springs 29, arrest the brushes and so allow the rings 4, 4<1> to move axially away from the brushes. For large motors, three rings may be used instead of two as shown.
